Abstract
Rice root growth under intermittent and flooded irrigation conditions was studied based on a root-box experiment.The result showed that rice in intermittent irrigation had higher root activity,more root biomass,deeper root distribution and more root biomass in the lower 10 cm soil layer after heading stage than in flooded irrigation.This might be one of the important physiological causes leading to high N absorption,dry matter accumulation and yield in intermittent irrigation treatment.
